[Ab] Resumo:Migratory birds are considered as vectors of infectious diseases, owing to their potential for transmitting pathogens over large distances. The populations of barn swallow (Hirundo rustica) migrate from Southeast Asia to the Japanese mainland during spring and migrate back to Southeast Asia during autumn. This migratory population is estimated to comprise approximately hundreds to thousands of individuals per year. However, to date, not much is known about the gastrointestinal microbiota of the barn swallow. In this study, we characterized the fecal bacterial community in barn swallow. Using 16S rRNA gene metagenomic sequencing analysis, we examined the presence and composition of potentially pathogenic bacteria in the fecal samples, which were collected during spring season from Osaka. The number (±S.D.) of total bacteria was approximately 2.1(±3.4)×10 per gram of feces. In most samples, the bacterial community composition was dominated by families, such as Enterobacteriaceae, Pseudomonadaceae, Mycoplasmataceae, Enterococcaceae, Streptococcaceae, and Alcaligenaceae. However, no relationship was found between the bacterial community composition and geographical area in the fecal samples. Potentially pathogenic bacteria were detected at the rate of >0.1%, which included Pseudomonas spp., Escherichia/Shigella spp., Enterobacter spp., Yersinia spp., Mycoplasma spp., Enterococcus spp., Achromobacter spp., and Serratia spp. Our results suggested that barn swallow is instrumental in the transmission of these genera over large distances.

[Ab] Resumo:A novel coccus-shaped, Gram-stain-positive, non-motile and facultative aerobic bacterium, designated strain D7T301T, was isolated from the small intestine of a marten, Martes flavigula, which was killed on the road in Pocheon-si, Gyeonggi-do, Republic of Korea. Grown on a tryptic soy yeast agar plate, colonies had a creamy colour and irregular form. The new isolate formed a monophyletic clade with Vagococcus penaei CD276T on a phylogenetic consensus tree based on the 16S rRNA gene sequence. The isolate grew optimally at 37 °C and pH 7 in the presence of 0.5 % (w/v) NaCl. The isolate was catalase- and oxidase-negative. The cell-wall peptidoglycan was type A4α l-Lys-d-Asp. The major cellular fatty acids were C16 : 0, C14 : 0, and C16 : 1ω9c. The predominant respiratory quinone was menaquinone MK-7 (85.1 %). The DNA G+C content based on genome sequencing was 33.8 mol%. The average nucleotide identity value obtained from comparative genomic analysis between strain D7T301T and V. penaei CIP 109914T was 72.6 %. On the basis of the phenotypic, phylogenetic, biochemical, chemotaxonomic, and genotypic analyses, Vagococcusmartis is proposed as a novel species of the genus Vagococcus. The type strain is D7T301T (=KCTC 21069T=JCM 31178T).

[Ti] Título:Genetic characterization of fecal impacts of seagull migration on an urban scenery lake.

[Ab] Resumo:A microbial source tracking scheme was devised to differentiate fecal impacts of seagulls from that of human activities on an urban scenery lake in southern China, which is a major wintering ground for the black-headed seagull. Fecal contamination of seagulls was characterized by quantifying a novel genetic marker targeting Catellicoccus marimamalium. Quantification of this marker was combined with those of Escherichia coli, human-associated Bacteroidales, thermophilic Campylobacter and Helicobacter. Findings of a year-round study indicate that C. marimamalium levels correlated strongly, both spatially and temporally, with seagull migration. A steady increase in C. marimammalium concentrations was recorded between October 2014 and March 2015, which peaked at about 5-log copies/100 mL in January. However, a background level of about 2.1-log copies/100 mL was noticeable from April through September when seagulls were absent, probably due to other host sources or secondary habitats for C. marimammalium. Seagull migration also caused an apparent elevation of E. coli concentrations (86% and 60%, respectively for qPCR and culture method; p < 0.001) as well as Campylobacter and Helicobacter (66% and 68%, respectively; p < 0.001). Nonetheless, in contrast to the declining levels of E. coli, Campylobacter and Helicobacter, the human-specific Bacteroidales marginally increased in the seagull-absent season, indicating a limited influence of human activities, compared with seagull migration, on the seasonal variations in microbial water quality of the lake. The elevated levels of FIB, Campylobacter and Helicobacter along with C. marimammalium may imply human health risk of the lake water due to seasonal seagull migration, which requires further investigation for risk assessment.

[Ab] Resumo:A Gram-stain-positive, non-motile, coccus-shaped bacterium, designated strain C25T, was isolated from the soil beneath a decomposing pig carcass in Korea and was characterized using a polyphasic taxonomic approach. Comparative 16S rRNA gene sequence analysis showed that strain C25T belongs to the genus Vagococcus in the family Enterococcaceae of the Lactobacillales. 16S rRNA gene sequence analysis showed that strain C25T was closely related to Vagococcus lutrae CCUG 39187T (96.5 % similarity) and Enterococcus termitis LMG 8895T (95.8 %). The chemotaxonomic properties of strain C25T were consistent with those of the genus Vagococcus; the major cellular fatty acids consisted of C16 : 0, C16 : 1ω9c and C18 : 1ω9c, and the cell-wall peptidoglycan type was based on meso-diaminopimelic acid. The G+C content of the genomic DNA was 44 mol%. On the basis of phylogenetic inference, fatty acid profile, and chemotaxonomic and other phenotypic properties, strain C25T is clearly differentiated from closely related type strains of the genus Vagococcus and represents a novel species in this genus, for which the name Vagococcus humatus sp. nov. is proposed. The type strain is C25T (=KEMB 562-002T=JCM 31581T).

[Ab] Resumo:Fermented soybean foods contain nutritional components including easily digestible peptides, cholesterol-free oils, minerals, and vitamins. Various fermented soybean foods have been developed and are consumed as flavoring condiments in Asian regions. While the quality of fermented soybean foods is largely affected by microorganisms that participate in the fermentation process, our knowledge about the microorganisms in soybean pastes manufactured in Northeast China is limited. The current study used a culture-independent barcoded pyrosequencing method targeting hypervariable V1/V2 regions of the 16S rRNA gene to evaluate Korean doenjang and soybean pastes prepared by the Hun Chinese (SPHC) and Korean minority (SPKM) populations in Northeast China. In total, 63399 high-quality sequences were derived from 16 soybean paste samples collected in Northeast China. Each bacterial species-level taxon of SPHC, SPKM, and Korean doenjang was clustered separately. Each paste contained representative bacterial species that could be distinguished from each other: Bacillus subtilis in SPKM, Tetragenococcus halophilus in SPHC, and Enterococcus durans in Korean doenjang. This is the 1st massive sequencing-based study analyzing microbial communities in soybean pastes manufactured in Northeast China, compared to Korean doenjang. Our results clearly showed that each soybean paste contained unique microbial communities that varied depending on the manufacturing process and location.

[Ti] Título:Influence of yeast and lactic acid bacterium on the constituent profile of soy sauce during fermentation.

[Ab] Resumo:Soy sauce is a Japanese traditional seasoning composed of various constituents that are produced by various microbes during a long-term fermentation process. Due to the complexity of the process, the investigation of the constituent profile during fermentation is difficult. Metabolomics, the comprehensive study of low molecular weight compounds in biological samples, is thought to be a promising strategy for deep understanding of the constituent contribution to food flavor characteristics. Therefore, metabolomics is suitable for the analysis of soy sauce fermentation. Unfortunately, only few and unrefined studies of soy sauce fermentation using metabolomics approach have been reported. Therefore, we investigated changes in low molecular weight hydrophilic and volatile compounds of soy sauce using gas chromatography/mass spectrometry (GC/MS)-based non-targeted metabolic profiling. The data were analyzed by statistical analysis to evaluate influences of yeast and lactic acid bacterium on the constituent profile. Consequently, our results suggested a novel finding that lactic acid bacterium affected the production of several constituents such as cyclotene, furfural, furfuryl alcohol and methional in the soy sauce fermentation process.

[Ti] Título:Safety assessment of Tetragenococcus halophilus isolates from doenjang, a Korean high-salt-fermented soybean paste.

[La] Idioma:eng
[Ab] Resumo:We assessed the safety of 49 Tetragenococcus halophilus strains isolated from doenjang in Korea. Minimum inhibitory concentration assays showed that all strains can be considered as susceptible to ampicillin, erythromycin, penicillin G, tetracycline, and vancomycin, but resistant to ciprofloxacin based on the Enterococcus breakpoint values provided by the European Committee on Antimicrobial Susceptibility testing in 2015. Ciprofloxacin resistance was sufficiently high to consider the potential for acquisition of transmissible determinants. Two strains exhibiting potentially acquired resistance to chloramphenicol and gentamicin, and chloramphenicol alone, were identified. None of the strains exhibited α-hemolytic activity or biofilm formation; two strains exhibited weak ß-hemolytic activity. Doenjang isolates produced an average of 3338.6 ppm of tyramine in the laboratory, considerably higher than the levels produced by two reference strains. All of the test strains exhibited similar cadaverine, histamine, and putrescine production patterns. Most T. halophilus strains could grow at a NaCl concentration >18%, exhibited acid production at 15% NaCl, and expressed strain-specific protease and lipase activities. The potential acquisition of transmissible determinants for antibiotic resistance and tyramine production identified in this study necessitate the need for a thorough safety assessment of T. halophilus before it can be considered for use in food fermentation processes.

[Ti] Título:Food to some, poison to others - honeybee royal jelly and its growth inhibiting effect on European Foulbrood bacteria.

[La] Idioma:eng
[Ab] Resumo:Honeybee colonies (Apis mellifera) serve as attractive hosts for a variety of pathogens providing optimal temperatures, humidity, and an abundance of food. Thus, honeybees have to deal with pathogens throughout their lives and, even as larvae they are affected by severe brood diseases like the European Foulbrood caused by Melissococcus plutonius. Accordingly, it is highly adaptive that larval food jelly contains antibiotic compounds. However, although food jelly is primarily consumed by bee larvae, studies investigating the antibiotic effects of this jelly have largely concentrated on bacterial human diseases. In this study, we show that royal jelly fed to queen larvae and added to the jelly of drone and worker larvae, inhibits not only the growth of European Foulbrood-associated bacteria but also its causative agent M. plutonius. This effect is shown to be caused by the main protein (major royal jelly protein 1) of royal jelly.

[Ab] Resumo:The objectives of this study were to assess the microbiological and physical/chemical quality of water in broiler turkey farms in the province of Khemisset (north-western Morocco) and, based on a questionnaire, to ascertain potential risk factors for contamination of drinking water with faecal coliforms. A total of 80 samples were collected and analysed in 20 farms (four from each farm). At the main inlet to the water line at the entrance to each turkey house, 100% of the samples were of unacceptable quality in terms of faecal coliforms, Escherichia coli, faecal streptococci, sulphitereducing anaerobes and enterococci. A significant reduction in microbiological contamination of the water line (p < 0.05) was observed on Day 60. While more than 90% of the samples were of satisfactory quality in terms of pH, nitrites, conductivity, nitrates and iron, only 35% were satisfactory in terms of total hardness and only 20% met quality standards for ammonium content. The factors affecting levels of contamination with faecal coliforms were water chlorination (p = 0.065; odds ratio = 14; 90% confidence interval [CI] = 1.14-71), cleaning and disinfection (p = 0.028; odds ratio = 14; 95% CI = 1.25-156.6) and antibiotic treatment (p = 0.001; odds ratio = 6; 95% CI = 2.1-35.2). To improve water quality in poultry farms, farmers are advised to protect wells from contamination and to install water purification units (pre-oxidation, coagulation, flocculation, disinfection). In addition, turkey houses and rearing equipment should be rigorously cleaned and disinfected between each batch of birds.

This pest is an invasive species and is currently distributed in some provinces of China. To recover the symbiotic bacteria of B. dorsalis from different invasion regions in China, we researched the bacterial diversity of this fruit fly among one laboratory colony (Guangdong, China) and 15 wild populations (14 sites in China and one site in Thailand) using DNA-based approaches. The construction of 16S rRNA gene libraries allowed the identification of 24 operational taxonomic units of associated bacteria at the 3% distance level, and these were affiliated with 3 phyla, 5 families, and 13 genera. The higher bacterial diversity was recovered in wild populations compared with the laboratory colony and in samples from early term invasion regions compared with samples from late term invasion regions. Moreover, Klebsiella pneumoniae and Providencia sp. were two of the most frequently recovered bacteria, present in flies collected from three different regions in China where B. dorsalis is invasive. This study for the first time provides a systemic investigation of the symbiotic bacteria of B. dorsalis from different invasion regions in China.
